Antonio Garzya (born 22 January 1927 in Brindisi, died 6 March 2012 in Telese Terme) was an Italian classical scholar, philologist, and university professor.

Emeritus professor of Greek literature at the University of Naples Federico II, he was a specialist of ancient Greek and Byzantine studies.

After attending the P. Colonna Gymnasium in Galatina (province of Lecce) and the G. Palmieri Lyceum in Lecce, Garzya studied Classical Philology at the University of Naples. He took his degree with a thesis on Andromache by Euripides.

In 1953 he started his teaching career, which he pursued from 1954 until 1966 in public secondary schools.

In 1960 he became an instructor of Byzantine Philology and Papyrology at the University of Naples. From 1965 until 1966 he was a school principal and then interrupted that activity from 1966 to 1968 to be Professor of Byzantine Studies at the University of Macerata, where, at the same time, he taught Latin literature. From 1969 to 1980 he was a professor of Byzantine Philology at the University of Naples. At the same time, from 1973 to 1983, he taught Philology of Medieval and Modern Greek and in 1976 was guest professor of Byzantine Studies at the University of Vienna. In 1981, he moved his professorship to the first chair of Greek Literature of the University of Naples and from 1984 to 1988 was Associate Professor of Medieval Greek at the Sorbonne in Paris. In 1993 he became a member of UPRESA 8062 “Médecine grecque” (formerly URA 1255) des CNRS in Paris. In 1997 he retired from his teaching duties and was nominated Emeritus shortly after.
